Rain washes out play in Buenos Aires

Rain washed out play at the Copa Claro clay-court tournament Friday, forcing organizers to schedule both the quarterfinals and semifinals for Saturday.

Only one quarterfinal got started Friday. The match between No. 4 seed Albert Montanes and No. 8 seed Juan Ignacio Chela was suspended in the third set at 3-all.

The three other quarterfinals will be played early Saturday - Nicolas Almagro vs. Jose Acasuso, David Nalbandian vs. Tommy Robredo, and Juan Monaco vs. Stanislas Wawrinka - with the semifinals set for the evening.
